File creation with requester-specified backing

A method comprising:

• receiving a request to create a new file on a file system that is backed by a specified set of existing data storage objects stored on a set of memory components;
• in response to receiving the request to create the new file:
• creating the new file by generating a file data structure on the file system that represents the new file, the file data structure comprising a mapping to the specified set of existing data storage objects, and an existing data storage object n the specified set of existing data storage objects comprising at least one of:
• a block device storage object of the set of memory components;
• or
• a data storage object that is associated with a log structured merge tree d structure stored on the set of memory components;
• and
• responding to the request with data that confirms creation of the new file on e file system;
• and
• causing the new file to be mapped into volatile memory.

A non-transitory machine-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a request to create a new file on a file system that is backed by a specified set of existing data storage objects stored on a set of memory components;
• in response to receiving the request to create the new file:
• creating the new file by generating a file data structure on the file system that represents the new file, the file data structure comprising a mapping to the specified set of existing data storage objects, and an existing data storage object in the specified set of existing data storage objects comprising at least one of:
• a block device storage object of the set of memory components;
• or
• a data storage object that is associated with a log structured merge tree data structure stored on the set of memory components;
• and
• responding to the request with data that confirms creation of the new file on the file system;
• and
• causing the new file to be mapped into volatile memory.
